Analysis of the anomalous magnetic mineral intensities and geochemistry for placer gold deposits are presented for those of the Attock area at the confluence of the Indus and Kabul rivers in northwestern Pakistan. Two grids covering an area of 10×18 m² and 8×10 m² were analyzed using a G‐858 Cesium Vapor Magnetometer. The anomalous zones obtained were plotted on contour maps, 2D and 3D magnetic intensity maps. Based on the magnetic anomalies, grid‐1 of the study area was sampled at three different anomalous zones for geochemical analysis. These zones contain gold concentrations, ranging from 2.11 ppm to 6.109 ppm with an average of 4.01 ppm. Increase in gold concentration in the subsurface within the anomalous zones indicates that magnetometer survey followed by a geochemical analysis can potentially narrow down the gold‐bearing anomalous zones.

通过综合地球物理和地球化学技术在印度西北部的印度河和喀布尔河交汇处勘探砂金矿床

在巴基斯坦西北部的印度河和喀布尔河交汇处，对Attock地区的砂金矿床的异常磁性矿物强度和地球化学进行了分析。两个网格分别覆盖10×18 m ²和8×10 m ²使用G‐858铯蒸气磁力计进行了分析。将获得的异常区域绘制在等高线图，2D和3D磁强度图上。根据磁异常，在三个不同的异常区域对研究区域的grid-1进行了采样，以进行地球化学分析。这些区域的金浓度范围为2.11 ppm至6.109 ppm，平均为4.01 ppm。异常区内次表层中金的浓度增加表明，磁力计测量和随后的地球化学分析可能会缩小含金异常区的范围。
